摘要：

Molecular wheels: Decacoordinated molecular wheels, Ta©B 10 - (see picture) and Nb©B 10 -, showing the highest coordination number for the central atom in a planar environment at present, were produced in a laser-vaporization supersonic molecular beam and characterized by photoelectron spectroscopy and ab initio calculations. The highly symmetric Ta©B 10 - and Nb©B 10 - anions are doubly aromatic with six delocalized π-electrons and ten delocalized I-electrons. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
